ipod kinda messed up??

Not sure if this the right section to post this but... my ipod nano's (the slim one. the version without a camera) clickwheel and button stopped responding. The strange thing is, when I put it in my dock, everything works, then stops when I take it out. By the way, I don't think I have warranty. I could but I don't know. Any solutions?

Sounds like mine, it's partially broken.One solution is to reformat it and re-sync.

Tried it and it didn't work...

Replaced the battery?
